The singer's burgeoning bump – she is due in late August/early September – didn't stop her from looking a knock-out.
Dressed in fitted leather trousers, a black top and embellished leather jacket, the Black Eyed Peas singer looked as sensational as ever, with her trademark blonde locks making waves around her face.
Her handsome husband was dapper as he affectionately held his arm around her and tenderly touched her round tummy.
Josh, the lead star of the film, was sizzling in a brown suit as he posed on the red carpet for his upcoming thriller, which also stars Dan Fogler and Miracle Laurie and is set to hit screens on 23 August.
The pair looked as loved up as ever. Not only are they expecting their first child together, but the 38-year-old has also just legally changed her name to take the surname of her Transformers actor husband Josh, who she wed in 2009.
The Big Girls Don't Cry star, born Stacy Ann Ferguson, officially became Fergie Duhamel following a court hearing on 16 August.
Fergie's lawyer said that the pop star had wanted to change her name for several years so that she can "conform to the first name which she is commonly and professionally known as, and has been for many years."
The pair are clearly enjoying the parents-to-be period, throwing not one but two baby showers.
The star-studded celebrations were attended by the likes of Fergie's Black Eyed Peas bandmates, will.i.am and apl.de.ap, who she posed with for a photograph, calling them "uncles" of her future son.
